Why are the halogen low beams on a new car particularly scattered?

[DeAdriana]

The reasons why the halogen low beams on a new car are particularly scattered: the bulb is not installed properly; the reflector inside the headlight is substandard, which is a quality issue with the light itself. Lifespan of car halogen headlights: Approximately 4 to 6 years, theoretically with a cumulative usage time of about 300 hours. If you drive at night three times a week, the lifespan would be around this duration. However, this depends on the frequency of night driving and the usage time of the headlights (day or night). The biggest drawback of halogen lights is their relatively low brightness, which may not meet the requirements of owners who demand high lighting performance. Their greatest advantage is their low cost and good penetration. Halogen bulbs are the most common type in cars: They operate on the same principle as the incandescent bulbs previously used in homes. The bulb contains iodine and bromine gases along with a tungsten filament. When electrically heated, the tungsten filament emits light. As the filament heats up, it sublimates tungsten, which reacts with the iodine and bromine gases. Upon cooling, the tungsten re-solidifies onto the filament, preventing premature breakage of the tungsten filament.
